onnecting to amplifier
The way you connect your C-range speakers to your amplifier depends on the type of installation that you are
making and the type of amplifier used.
C
ables
To get the best possible performance from your C-range speaker, use high quality cable. Cables with high
capacitance, high inductance and high impedance have a strong negative influence on sound quality as well as
amplifier reliability.
Mach Speakers A/S recommend 2x4 mm (11 AWG) or 4x4 mm (11 AWG) Mach speaker cable. This is a professional
rubber cable that is waterproof, has low impedance, low inductance and low capacitance. It also has a low sulfur
content that ensures minimum cable oxidation. The cable is very soft and easy to wind. For recommended cable
lengths, please see table.
Recommended cable lengths (damping factor = 50)
S
imple connection
The most basic type of connection is a direct connection from one channel on the amplifier to one speaker. In
this case connect the [+] terminal on the amplifier to the [+] terminal on the speaker and the [-] terminal on the
amplifier to the [-] terminal on the speaker.
